SPINNING FRAME.

Application fi led March 10, 192a. Serial No. 542,675.

' To all whom it may concern:

Be it known that I, ARTH R C. VARNUM, a citizen of the United States,residing at Southbridge, in the county of VVo-rcester and Commonwealthof Massachusetts, have invented new and useful Improvements in aSpinning Frame, of which the following, together with the accompanyingdrawings, is a specification. i

My invention relates particularly ,to cap spinning frames and has forits object to provide improvements in the construction and arrangementof the thread guiding means and associated .parts, whereby the spinningframe as a. whole'willbe rendered more effective in its operation.-

Among the advantageous results obtained by the use of my invention, arethe substantial elimination of the collection of fly around the threadguides during the operation of the machines, and the possibility ofturnin of the others while spinning, or of liftin all of the threadguides in unison when do ing. A still further advantage of my improvedconstruction lies in thefact that the separator plates between adjacentcaps and spindles are extended above the line of the thread guides so asto substantially eliminate the possibility of double spinning. inaddition to performing their usual function, that is, the prevention ofthe yarn from adjacent caps from becoming entangled due to theballooning action of the yarn. The above, and other advantageousfeatures of my invention will hereinafter more fully appear, referencebeing had to the accompanying drawings in which,

Fig. 1 is a view in end elevation of a portion of a spinning frameembodying my invention.

Fig. 2 is a view in front elevation of the parts shown in Fig. 1. r

Fig. 3 is a plan view of the parts shown in Fig. 1.

Fig. 4 is a fragmentary view in side elevation showing one of myimproved thread guides on an enlarged scale.

Like reference characters refer to like parts in the different figures.

Referring to Fig. 1, the roller beam of a spinning frame is indicated at1, to which is secured a thread board 2. A lifter'bar 3 is secured tothe front edge of the thread board 2 by hinges 4, as best shown in Fig.

each thread guide independently 3. A'plurality of hinge brackets 5' arefsecured to th front face of the bar 3, each bracket providing apair ofears 6 between which is pivotally mounted a thread guide. or pot-eyeholder 7 by means of a pin 8. As best shown in Figs. 3 and 4, eachholder 7 consists of a strip of metal bent back on itself where itenters between the ears 6, opposed portions ofrthe strip being curvedoutwardly as indicated at 9 to provide a seat for the reception of apot-eye or guide 10 which is providedwith a top flange 11 supported bythe portions 9. Each poteye 10 is preferably formed of porcelain, orother similar smooth and durable material, and is provided with acentralthread opening 12 and a slot 13 communicating therewith. The sideportionsof the holder 7 extend outwardly beyond the pot-eye seat toprovide flaring wing portions 14 for guiding the thread into the opening12.

The pot-eye holder 7 normally occupies V the position shown in Figs. 1and 2,'so that the pot-eyes 10 are positioned for) convenlentlyreceivlng threads from the drawing rolls 15, only one pair of which isshown.

The thread opening 12 of each pot-eye 10 is thus held substantially inalinement with the vertical axis of a spindle or of a cap and spindle16, a thread] 17 being shown in Fig. 1 as passing between the rolls 15through a pot-eye to the spindle 16. With the above described'arrangemetnt it is obvious that each holder 7 may be lifted about itspivot pin 8 into the position shown in dotted lines in Fig. 1 at anytime during spinning, or all o of the holders 7 may be lifted in unisonbyturning the bar 3 on its hinges 4 into the position shown in dottedlines in Fig. 4

a when it is desired to doff the machine, as a whole. When an individualholder 7 is lifted, as shown in Fig. 1, it returnsto its originalposition as soon as it is released, whereas when all of the holders 7are lifted by thebar 3, as shown in Fig. 4, the holders will fall backinto the position shown and remain out of the way during the operationof dofling. V

A plurality of spaced separator plates 18 are arranged between adjacentcaps and spindles 16, each plate 18 extendingfrom a point near the loweredge of a cap upwardly into the spaces between adjacent pot-eye holders7. Each plate 18 is provided with a notch 19 for receiving the bar 3 andthe Q v r 1,494,825

double the desired size as frequently occurs when the pot-eyes aremounted on a continuous board with nothing interposed between adjacentpot-eyes, as in previous constructions.

Tith my improved. arrange ment of separate pot-eye holders 7 it ispossible to extend the'separator plates upwardly between adjacentholders as far as is From the foregoing, it is apparent that I haveprovided an improved arrangement of the parts of a cap spinning framewhereby it is possible to lift the thread guides, or pot-eyes, eitherseparately or in unison, as desired, my improved construction being suchthat there are no flat surfaces adjacent to the thread guides for thecollection of fly or lint. hfy construction further includes the use ofseparator plates between adjacent caps and) spindles which extend from apoint near the lower edges of the caps upwardly above the pot-eyeholders and thereby effectively prevent double spinning, as well aseliminating the bad efiects of the ballooning ofthe yarn.

IVhile I have shown my inventionas applied to a particular arrangementof parts, it is not so limited, but is susceptible of such modificationsand changes as may come withinthe scope of the appended claims.

I claim,

1. In a spinnlng frame, the combination with a plurality of spaced capsand spindles and a plurality of thread guides cooperating therewith, ofseparator plates extending between said caps and spindles and projectingabove the said thread guides.

2. In a spinning frame, the combination with a plurality of spacedcapsand'spind les and a plurality of thread guides cooperatingtherewith, of separator plates disposed between said caps and spindlesand extending from the lower portion of a cap to a point above ahorizontal plane passing through said thread guides.

3. In a spinning frame, the combination with a plurality of spaced capsand spindles and a plurality of thread guides cooperating therewith, ofseparator plates dispose-d between said caps and spindles and adapted toprevent double spinning and the entanglement of adjacent threads due tothe ballooning thereof.

4. In a spinning frame, the combination with a plurality of spaced capsand spindles and a plurality of thread guides cooperating therewith, ofseparator plates extending upwardly from between said caps and spindlesand adapted to--' prevent a broken thread from one thread guide enteringthe next adjacent thread guide.
